Inertial Navigation System(INS) can provide the vehicle position and velocity information using inertial sensor outputs without the use of external aids. Unfortunately INS navigation error increases with time due to inertial sensor errors, and therefore it is desirable to combine INS with external aids such as GPS, TACAN, OMEGA, and etc.. In this paper we propose an integration algorithm of commercial GPS/GLONASS and INS where an adaptive filter for signal processing of GPS/GLONASS receiver and the 12th order Kalman filter for aided strapdown INS(SDINS) we employed. Simulation results show that the proposed adaptive filter can effectively remove a randomly occurring abrupt jump due to sudden corruption of the received satellite signal and that the Kalman filter performs satisfactorily.
Penicillin 이 Sophora japonica L. 凝集素의 凝集活性에 미치는 影響에 關한 硏究
朴興源 大韓法醫學會 1986 대한법의학회지 Vol.10 No.1
After Stillmark's report on the agglutination of human and animal red blood cell by extracts of plant, Ricinus communis, numerous studies on phytagglutinin were performed. Phytagglutinins are divided into non-specific phytagglutinin, race-specific phytagglutinin, and type-specific phytagglutinin. In Korea, studies of phytagglutinins using Korean native plants were achieved widely and deeply by Moon et al. since 1968. So, the author performed the agglutination test with human RBC by using seed extract of Sophora japonica L., native to Korea, and studied on the change of agglutination activity of same material treated with various penicillin preparatives. The seed extracts of Sophora japonica L. react with human RBC as panphytagglutinin, and the results by using that of penicillin treated could be summarized as follows; 1. Human RBC could be divided into 2 groups by agglutination of extract of S. japonica L. treated with penicillin G natrium. In one group, agglutination was inhibited by penicillin specifically(18%), and not in the other group(82%). 2. Penicillin G natrium showed the most stable and repeatable agglutination inhibition reaction among the penicillin preparatives used in the study. 3. The agglutination inhibition property of penicillin to phytagglutinin, S.japonica L., had relation with ABO and H blood types.
